This invention pertains to containers and more especially to a tool for removing screw caps'froln same. -f

-In a particular form `of screw cap remover, a strap is attached to the end portion of ka handle and so attachable around the cap that it -may be manipulated in an eccentric manner and to be tightly bound on it at rst and then as the manipulation is increased, pulled around under the substantial leverage of the handle and unturned or turned on as the case may be. The disadvantage of this form is that its scope of use is limited to a particular size selected for it, and the leverage is limited to a particular length. In addition it cannot be attached quickly, and when the strap is damaged or worn the whole instrument has to be discarded.

It is therefore an object of this invention to provide a new and improved container cap clamp that will avoid one or more of the disadvantages and limitations of the prior art.

An additional object of the present invention is to provide a new and improved container cap clamp that will permit adjustments to be made in its power to operate and the size of the cap to be manipulated by it.

Another object of the herein described invention is to Vprovide a new and improved container cap clamp that will be structurally .designed to permit renewal or interchanging of its parts as worn or damaged.

A further object of the invention is to provide a new and improved container cap clamp that will be relatively simple and light in structure, easy to keep sanitary and adaptable for economical manufacture.

Other objects will become apparent as the invention is more fully set forth.

For a better understanding of the invention and the objects thereof, reference is made to the drawings of this invention, as well as the following description, as same outline a particular form of the invention by way of example. They serve to emphasize the principles employed in the invention and its operation, while the scope of the invention is especially pointed out in the claims.

In the construction shown in the drawings which embody the invention:

Figure 1 is a view in perspective showing the device embodying this invention positioned on a screw cap and jar;

Figure 2 is a front view of the device;

Figure 3 is a sectional view taken along line 3-3 of Figure 2, and Y Figure 4 is an end view looking in the direction of arrows 4-4 of Fig-ure 3.

Similar reference numerals refer to the same parts illustrated in the various gures in the drawings.

In the particular structure indicated, a clamp 2 f strap I0,is made of ilexible material'of suitable strength and quality. It is made of a length sufficient to take care of the manipulation of caps or covers of containers of various sizes. It is bent` into a loop as shown, with its end portions I I and I2 ,brought down parallel on each otheragainst the undercut back surface I3 of a handle I4. The portions II and I2 are provided with holes I5 and I6 aligned With each other longitudinally and suitable for the respective bolts I'I and I8 to pass therethrough. The bolts I1 and I8 also pass through the L-plate 20 and face plate 2|. The bolt I5 is preferably arranged with a screwthreaded wing nut 22. The bolt I8 is provided with a slot I9 which supports a cam-lock 24 rotatable on pin 25 passing transversely through the bolt. This cam-lock 24 gives a very expeditious operation when applying the clamp strap II. The handle I4 is provided with a depression 29 in the form of a channel. An elongated slot 2i is positioned in the back surface I3 of the handle to allow the bolts I'I and I8 to be moved therein to adjust the clamp strap Ill to suit the jar cap being removed. The depression 29 is deep enough to partially encase the plate 2|, lock 24 and wing nut 22 below the upper face of the said handle. The L-plate 28 keeps the ends of the strap aligned and limits the amount of compression to be placed on the strap portions II and I2 by the bolts. The slot 26 permits a great deal of longitudinal adjustment to the strap to suit the size of cover it is to be used with and clamp around. The handle has a humped saddle 21 at one end, that is olset from the general longitudinal axis of the handle, to allow it to gradually contact the exterior surface of the strap when applied on a cover. This saddle 21 engages the strap I0 and tends to compress the loop into a shorter form. This tightens up on theV cover and permits the handle I4 to exert its leverage at the same time.

The greater the leverage exerted, the greater becomes the clamping action and friction induced thereby. This happens in every instance of use, regardless of the size of cover it operates on.

When out of use the bolts may be loosened and the plates with the strap I0, pushed further down the slot 26 in the handle, to reduce the amount of room it will take up. The material of the strap may beof a metal strip or fabric cloth of the proper type. The strap is normally looped over the cover loosely and then automatically tightened as the device is manipulated.

While but one general form of the invention is shown in the drawings and described in the speciiications, it is not desired to limit this application for patent to this particular form or in any other way otherwise than limited by the scope thereof, as it is appreciated that other forms of construction could be made that would use the same principles and come within the scope of the appended claims.

Having thus described the invention, what is claimed is:

1. A container cover clamp comprising a strap of flexible material having its ends brought together forming a loop for enclosing a container cover, a handle for manipulating the loop so asM to tighten it on the cover, means for; adjnsting the size of loop to suit the cover to be engaged',A
